Figure 1.

A. Axial CT image shows a 2.2 cm right upper lobe lesion; B. Image during microwave ablation shows a single microwave probe positioned within the tumor; C. Immediate post-ablation image shows groundglass opacity surrounding the lesion, which is penetrated by probe tracts; D. Follow-up CT image 3 months after microwave ablation shows a larger consolidation consistent with expected post-ablation change; E. CT at 9-month follow-up shows near resolution of consolidation with residual parenchymal scar.
